I'm having the same issue with the sword and shield bonus after the patch. After being affected with the double click bug a couple of days ago I reloaded from the point before this happened and have not double clicked on equipment since then. However I noticed now that it's happened again even though I haven't double clicked any equipment. Both Edér and my main PC are affected. Edér can be fixed by removing and adding back to the party but I guess that the console is the only option right now for fixing my main.
